Russia warned the US about the attacks of US-backed forces in Syria against Syrian government forces. Retaliation will be sought if the same attacks are made in the future.

Syrian Democratic Force (SDF) made attacks against Syrian Arab Army, government forces supported by Russia in Deir ez-Zor. The attacks which have also occurred before were made by forces under the support of US troops in the region. SDF is mostly comprised of Kurdish militia and claims to be fighting against ISIS terrorists.

Major General Igor Konashenkov, the Russian Defense Ministry’s spokesman, said that the US commanders were recurrently warned about the SDF provocative movements. “Russia unequivocally told the commanders of US forces in Al Udeid Airbase (Qatar) that it will not tolerate any shelling from the areas where the SDF are stationed,” Konashenkov added.

Suspicion over SDF’s collusion with ISIS forces were also mentioned in Konashenkov’s talks. He asserted that there are signs that SDF refrains from fighting ISIS militants in multiple fronts in Deir ez-zor.

Russia detected the transfer of SDF fighters from the IS stronghold of Raqqa, to join forces with the militants. SDF militants work to the same objectives as IS terrorists. Russian drones and intelligence have not recorded any confrontations between IS and the ‘third force,’ the SDF.

Siege of Raqqa was terminated by the ISIS following advances by Syrian Government forces in the region. “The central parts of the former ISIL capital, which account for roughly 25 percent of the city, remain under full control of the terrorists,” Konashenkov explained.

According to a statement issued by Mr. Konashenkov, Deir ez-Zor has been liberated by more than 85 percent so far and the final blows on the body of ISIS is being made these days. The US and its western allies’ attempts to hinder the fast operation of Syrian government backed by Russia and Iran in Syria have failed so far.
